Note 2: VOS is measured one minute after application of power.
Note 3: Long-term Input Offset Voltage Stability refers to the average trend line of VOS vs. Time over extended periods after the first
30 days of operation. Excluding the initial hour of operation, changes in VOS during the first 30 operating days are typically
2.5µV – refer to typical performance curves.
Note 4: Guaranteed by design.
